Help! Home Sharing on IPad 3.

Hello! I cannot seem to get home sharing to work (particularly videos) on my iPad 3. It is activated and set up in iTunes, but the problem is, I cannot find the shared videos button in the videos app. Here is a picture:
As you can see, there is only the "store" button. Where could the shared tab be hiding? The apple tutorials are particularly unhelpful as none of them are updated to iOS 5, so they all require the "iPod" app, which was removed.

If it's any help, there is no shared section in the music app either, not even under the "more" tab.

The only other thing I can think of is if the movies are AVI files. Those work with iTunes, but not your iPad, that could be a reason they don't show up on your iPad. Handbrake would fix that for free.

One other thing that may happen is if the video file is checked as "part of a compilation" they sometimes don't show up on the iPad.
